Answer:
heart rate is 68-to-92 beats per minute
Explanation:
An individual's maximum heart rate can be estimated by using the formula: 220 &150 age in years = MHR. Pulse rate can then be monitored while an exercise is being done and the % MHR calculated to assess intensity.
So, for example, the estimated MHR for a 50-year-old individual would be 220 - 50, or 170. Let's say that an individual's heart rate measured 100 beats per minute performing a certain activity. Since 100 is approximately 59% of the MHR (170), that would be considered a moderate level of exercise. The overall levels of intensity for a 50-year-old would be as follows:
Low intensity: heart rate is 68-to-92 beats per minute.
Moderate intensity: heart rate is 93-to-118 beats per minute.
High intensity: heart rate is more than 119 beats per minute.
